If multiple scopes match the referrer URL, then the most specific scope path is used (the scope key name with the longest name).
The browser falls back to the next most specific scoped path if there is no matching specifier, and so on, eventually falling back to the module specifier map in the `imports` key.
+### Integrity metadata map
+
+You can use the `integrity` key to provide mapping for module [integrity metadata](/en-US/docs/Web/Security/Subresource_Integrity#using_subresource_integrity).
+This enables you to ensure the integrity of dynamically or statically imported modules.
+`integrity` also enables you to provide a fallback for top-level or preloaded modules, in case they don't already include an `integrity` attribute.
+
+The map keys represent module URLs, which can be absolute or relative (starting with `/`, `./`, or `../`).
+The map values represent integrity metadata, identical to that used in [`integrity`](/en-US/docs/Web/HTML/Element/script#integrity) attribute values.
+
+For example, the map below defines integrity metadata for the `square.js` module (directly) and its bare specifier (transitively, via the `imports` key).
